After playing memnite with other people, it became clear that with low player counts, the action is very spread out. So we decided to split it into two maps: one map with only the Tower Ring and another map with the Cave Ring. We then turned it into the night for these two maps.

The Ring Control gameplay is different from any other map you've played, except memnite, but it's still fairly simple. Red and Blue fight for contorl of the Ring, while Yellow snipes everyone. Red and Blue can use jump pads to jump up high and through the ring. Flying through the air like this is where the sniping is a lot of fun.

Memnate is the Tower Ring from memnite_r. The snipers spawn inside the tower and then they can teleport up to windows so they can snipe the Red and Blue players. All the action takes place in a huge, wide-open, outdoor area with a few things to take cover behind.

Anyway, download it and have fun.
